Question
Copper can be deposited from acidified copper sulphate and alkaline cuprous cyanide. If the same current is passed for a definite time
Options
A.the amount of copper deposited from acidic copper sulphate will be higher
B.the amount of copper deposited from alkaline cuprous cyanide will be higher
C.the same amount of copper will be deposited
D.copper will not deposit in either case
Solution
$W = \frac{Q}{F} \times \frac{A}{n}$
For smaller n, w will be higher.
